Zimmerman's high-profile second-degree-murder trial in the shooting death of 17-year-old Trayvon Martin began June 10 and concluded July 13 with a not-guilty verdict. During the trial, Seminole County handled the "coordination of resources and planning," through its Emergency Operations Center, county spokesman Alan Harris said.

According to Harris, the EOC's role included "public information, safety, liaison, logistics, planning, intelligence" and other operations. Its efforts were spearheaded by a team of fire-rescue, facility management, information technology, utilities, economic development and public works staff, as well as law enforcement, he said.

"While the exact costs are still being recorded, Seminole County Government response to the trial, including all support and logistics, is estimated at $ 91,000," Harris said in Friday's statement.

Friday evening, the Seminole County Sheriff's Office said it spent $425,000 on the trial, a higher figure than a preliminary estimate provided last month. In addition, about $33,000 was spent on sequestering the Zimmerman jury.
